I am reasonably certain that the Geode CPUs have no VID pins, so it is
expected that this particular feature of the PC87366 isn't used on your
system.

The annoying "Requested unsupported VRM version" message that fills
your logs has been fixed in kernel 2.6.22. For earlier kernel versions,
there is no direct way to disable this warning message, but the
following workaround should work:

* Search for the "vrm" file under /sys. It should be reachable as
  either /sys/devices/platform/pc87366.26144/vrm
  or /sys/class/hwmon/hwmon0/device/vrm.

* Write value 90 to that file:
  echo 90 > /sys/devices/platform/pc87366.26144/vrm

After doing that, the warning message should no longer be logged.
You'll have to reiterate the operation after each reboot so you
probably want to add the command in some local boot script.
